The GSE electronic ballast can manage all kind of MH metal-halide and HPS high pressure sodium bulbs at 250-400-600W. A UV- acid- and waterproof foil build in LED indicate the status and on 3knobs you can change the wattage. By steps from 660W-600W-400W-250W or with push and hold even step less from 660W to 250W. GSE uses only finest high quality components such as aluminium casted long live and high temperature electrolytic capacitor, transistors PhilipsNXP, high frequency ISKRA components etc... and source >84% EU manufactured components. A extremely big-surface aluminium radiator keeps the running temperature low and provides a long life of the components. The high frequecy above 80kHz to 220kHz avoids acustic resonance of the bulb.

The ballast comes as a finish assembled product with 3m connector cable and 4m lamp cable to connect to the reflector E40. It is all waterproof sealed and have IP64 protection class.
